☀️ SPACE WEATHER

CURRENT STATUS — 14 JUNE 2026

  • CONTINUED HIGH-ENERGY ELECTRON ALERT — NOAA ALTEF3 serial 3700, issued 14 Jun 13:28 UTC: GOES-19 reports 2 MeV electron integral flux still above 1,000 pfu, with yesterday's maximum at 1,520 pfu; this alert has been continuous since 13 Jun 13:32 UTC.
  • The original electron enhancement episode began 16 May; peak fluxes reached 6,667 pfu on 19 May before gradually declining and briefly ending, then re-triggering on 6 June and again on 13 June.
  • A G3 (Strong) geomagnetic storm watch issued 3 June for 4-5 June was confirmed; K-index 7 warning was triggered 5 June 17:14 UTC, with sustained G2-G3 conditions through 5-6 June driven by the X1.0 flare (N17W19) and associated CME on 3 June.
  • The G2 watch for 13-14 June (issued 11 June, serial 275) was cancelled by NOAA on 14 June 08:30 UTC — G1 (Minor) conditions no longer expected.
  • K-index 4 alert was still active as of 13 June 21:00 UTC (serial 2666, threshold reached 13 Jun 20:59 UTC).
  • SOLAR FLARE RECAP FROM 3 JUNE — Three M-class events and one X1.0 flare (peak 11:28 UTC, R3 Moderate radio blackout) erupted from an active region near N17W19; an associated full-halo CME prompted the G3 watch.
  • CONDITIONS EASING — No new geomagnetic storm watches are currently in force; the electron flux alert remains the primary active alert as of 22:00 UTC 14 June.
  • Satellite operators should note the prolonged multi-MeV electron environment has persisted at elevated levels on and off for nearly a month.

📄 RESEARCH

UNIDENTIFIED SURFACE COMPOUND ON TITAN AND PLUTO

  • arXiv 2606.13350 (11 Jun): JWST spectroscopy of both Titan and Pluto reveals an absorption feature at 5.11 micrometers matching neither body's known inventory — a potentially novel surface material awaiting identification.

JUPITER ISOTOPE RATIOS FROM COMET SL9 LEGACY

  • arXiv 2606.13238 (11 Jun): New ALMA measurements of carbon and nitrogen isotope ratios in Jupiter's stratosphere trace the long-lasting chemical legacy of Comet Shoemaker-Levy 9, which hit Jupiter in 1994 — molecules deposited then are still detectable today.

NEAREST KNOWN STRIPPED SUPERLUMINOUS SUPERNOVA PROBED IN X-RAYS

  • arXiv 2606.13128 (11 Jun): Four Chandra X-ray observations of SN 2018bsz — the closest SLSN-I on record — constrain how a central engine such as a millisecond magnetar powers these extreme explosions and shape their ejecta structure.

GALAXY SIZE LINKS GAS INFLOWS TO METALLICITY

  • arXiv 2606.13124 (11 Jun): A new analysis shows that a galaxy's physical size encodes the connection between gas inflow rate and metal content, extending and explaining residuals from the well-known mass-metallicity relation.

POSSIBLE EXOPLANET MAGNETISM VIA WIND ASYMMETRY (SUPPORTING THEORY)

  • arXiv 2606.13291 (11 Jun): An automated method to detect fine structures along solar flare ribbons tracks plasmoid dynamics in flare current sheets — improving our ability to map where and how magnetic reconnection occurs during solar eruptions; relevant context for the active flaring seen 3 June.

COMPACT STAR CLASSIFICATION BY MACHINE LEARNING

  • arXiv 2606.13369 (11 Jun): Neural network models applied to gravitational-wave and multimessenger data classify neutron stars versus more exotic compact objects, offering a new tool to decode the equation of state of ultra-dense matter.
